Finding device for a MAC

When I look at the "Current DHCP Client Information" on my wireless router
(Buffalo WHR-HP-G54) it shows that an IP address has been assigned
(192.168.11.5) automatically to MAC 00:06:1B:C4:BC:F2. My network is
simple: DSL modem, Wireless Router, MIMO notebook adapter, Musical bridge.
The MAC for the router and musical bridge are written on the devices and are
not the one above. The DSL modem and notebook adapter do not have a MAC
address written on their devices. Would they even have a MAC? If they have
a MAC could it the one shown above? Could it be the MAC of an intrusive
connection to my network?

Hi
Writing the MAC address of a Device is optional, many devices that have MAC
number does not have it written on them.
DSL modem would not show a MAC address, but the Notebook network card must
have MAC whether it is written on it or not.
Run ipconfig on the laptop it would show its IP and MAC number, http://ezlan.net/ip_mac.html
As for Wireless, make sure that your security is On and there would be No
intrusions.
From the weakest to the strongest, Wireless security capacity is.
No Security
MAC
WEP
WPA-PSK
WPA-AES
WPA2
The documentation of your Wireless devices (Wireless Router, and Wireless
Computers Card) should state the type of security that is available with
your Wireless hardware.
All devices MUST be set to the same security level using the same pass
phrase.
Therefore the security must be set according what ever is the best possible
of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the
max. with WPA2, but one device is only capable to be configured to max . of
WEP, to whole system must be configured to WEP.
If you need more good security and one device (like a Wireless card that can
do WEP only) is holding better security for the whole Network, replace the
device with a better one.

All internet devices must have MAC addresses.

Here is the data on the MAC address in question.

Search results for "00:06:1B:C4:BC:F2"

MAC Address
Prefix Vendor
00061B Portable Systems, IBM Japan Co, Ltd

Was your "notebook adapter" made by IBM?

The router has at least 2 MAC addresses. One for the WAN (Internet) port
and one for the LAN ports.
